Portable measuring instrument for surface roughness Surftest SJ-220, Type: SJ220S

Series 178 – portable measuring instrument for surface roughness.
This is a portable measuring instrument that allows you to measure surface roughness easily and accurately.

The Surftest SJ-220S offers you the following advantages:

• Robust design, yet comfortable to use.
• The skid system enables user-friendly and intuitive menu navigation via the touchscreen.
• It operates independently of the mains supply, allowing measurements to be made on the move.
• The high-resolution 2.8-inch LCD touchscreen offers outstanding legibility.
• It performs roughness analyses in accordance with various international standards (DIN EN ISO 21920, DIN EN ISO 4287, DIN EN ISO 13565, ISO 12085, VDA, ASME, JIS).
• Different optional drive units expand the range of applications.
• Calculation results, assessed profiles and function curves such as BAC and ADC can be displayed.
• Support for 25 languages.
• Optional Bluetooth® connection to PC and smartphone.
• Free SJ Communication Tool software and Android SJ app available for download.
• The S type has a transverse sensing function. This can be used, for example, to measure connecting rod bearings on crankshafts.
